if You want to get When it Rains, it Pours achiev you need: Deal 800 total damage with a single use of Spike Guard in Quick or Competitive Play.
this is the same frustrating type of achievement as with Rapird Discord or Antipode. It is not about skill or learnig hero, it is just about to luck.
But after December 17, 2024 update is even more impossible to obtain because shorten duration of Spike Guard.
Blizzard achievmakers - maybe it is good time to change requirements for this achievement?
